Hackers have hit Valve's popular online gaming service Steam, stealing personal and probably financial information belonging to several thousand users.
The attack was discovered when Steam forum users started receiving dubious messages from a hacking website. It was later revealed that the forum had been compromised and the company said that it was investigating the hack.
Valve confirmed that the attack is deeper than earlier anticipated and goes ‘beyond' the forums. The company is yet to tell people to change their account passwords but has asked them to monitor their credit card statements nonetheless.
"We learned that intruders obtained access to a Steam database in addition to the forums. This database contained information including user names, hashed and salted passwords, game purchases, email addresses, billing addresses and encrypted credit card information," Valve's CEO wrote in a post.
"We do not have evidence that encrypted credit card numbers or personally identifying information were taken by the intruders, or that the protection on credit card numbers or passwords was cracked. We are still investigating," he added.
Valve said that there was no evidence that Steam account passwords had been compromised but asked users to change it anyways.
